take some measurments once you pull out the other one if the bolting paterns are the same or you can make them the same but the other one just hangs a bit lower then your fine, but it might be wider in which case it probably wont fit into the spot, so take measurments and then find one and measure it and if you'v got a little room to play with then go for it.

i have a brand new aftermarket tank that i will be pulling off in the next few weeks. it has about 300 miles on it so far. i'm switching over to a fuel cell. my car was made in 09/87, so if the tank will fit. i'm willing to get rid of both senders and the pump assembly with it. the pump is on its way out though.

the later model tank is way different, the ventilation is different and it has in-tank pumps instead of an external pump. You can make it work but you would have to have a whole later model car with all of the parts in it
